Overview

By default the Microsoft default dial plan does not route 000 emergency calls correctly. This results on emergency calls failing when the service is sending calls to a PBX ir Trunk.


Solution

The solution when using an upstream PBX or Trunk for handling emergency calling, is to create a custom dial plan in the Teams admin center as show in these three steps:

  1. Open the Global Dial PlanGraphical user interface, application Description automatically generated
  2. Add a new Normalization Rule with the settings set as per screenshot belowA screenshot of a computer Description automatically generated with medium confidence
  3.  Move the Emergency Normalization rule up to the top of the order and then click Save.

 


Important additional information

  • Teams may amend the behaviour of the dial plan and so this setting should be verified periodically.
  • Using Teams' custom emergency calling settings may affect the behaviour of this dial plan.
  • Using the Dynamic Emergency Trunk (DET) service provided by the platform may affect the behaviour of this dial plan so should be verified during the configuration of the DET service.
  • Review Microsoft Emergency calling terms and conditions regarding the use of emergency calling in Teams: https://docs.microsoft.com/en-us/microsoftteams/emergency-calling-terms-and-conditions
